M3.5 quake near Sedona is felt locally; preceded by foreshocks

Residents in the Sedona-Flagstaff area report feeling a magnitude 3.5 earthquake that hit about 6 - 10(?) miles north-northeast of Sedona at 2:19 a.m. local time this morning.

Dr. Jeri Young, who runs the Arizona Broadband Seismic Network here at AZGS, reports there were two smaller events in the area prior to the quake and one aftershock. The foreshocks were at 12:25 and 12:39 a.m. and the aftershock at 9:04 a.m. today.

She also says her preliminary epicenter location is further north, near the Munds Park fault, which may explain why so few people have thus far reported feeling the shaking. [Above, red star marks the USGS located epicenter, the labelled red circle is the AZGS-ABSN location. Credit, ABSN]
